Effect of drought stress on imbibition germination and seedling growth of Sophora alopecuroides

Objective To study the influence of drought stress on imbibition germination of Sophora alopecuroides and the drought resistance of its seedling.Methods To measure the imbibition rate,germination rate,germination index,seedling growth,and relative tissue moisture content under the drought stress by PEP-6000.Results With the increased level of stress,the imbibition rate,germination rate,germination index,vigor index,seedling hight,root length,and the relative tissue moisture content tended to decrease,while the seedling dry weight,root dry weight,and root-shoot ratio presented rising tendency then followed by the decrease.Conclusion The appropriate drought stress could improve the drought resistance of seedling,which is beneficial to cultivate strong seedling.
